The Cayley Isomorphism property for combinatorial objects was introduced by L. Babai in 1977. Since then it has been intensively studied for binary relational structures: graphs, digraphs, colored graphs etc. In this paper we study this property for oriented Cayley maps. A Cayley map is a Cayley graph provided by a cyclic rotation of its connection set. If the underlying graph is connected, the...

The MHC class I-related chain (MIC) A and MICB ligands for the activating receptor NKG2D can be shed from tumor cells, and the presence of these soluble molecules in sera is related with compromised immune response and progression of disease. Recently, thiol disulphide isomerases and members of the ADAM (a disintegrin and metalloproteinase) gene family were identified as key enzymes in mediatin...

Heteroresistance to antimicrobial agents may affect susceptibility test results and therapeutic success. In this study, we investigated heteroresistance to cephalosporins and penicillins in Acinetobacter baumannii, a major pathogen causing nosocomial infections. Two A. baumannii isolates exhibited heteroresistance to ampicillin-sulbactam, ticarcillin-clavulanic acid, cefepime, and cefpirome, sh...

Sexual behavior of male moths after prolonged exposure to the 1-ng pheromone/m(3) air previously measured in orchards treated with pheromone for mating disruption was examined in a flight tunnel. The exposure of Grapholita molesta (Busck) to 1-ng (Z)-8-dodecen-1-yl acetate (Z8-12:OAc)/m(3) air for 15 min had no effect on their ability to fly upwind to a conspecific, virgin calling female. Afte...

We analyze the energy distribution of the leptons coming from the top decay t t bH +, bW+ + bl+u. The correlation between the lepton energy distribution and the top spin may be useful for distinguishing the H+ signature from the W background. Such a correlation can also be useful for disentangling the two different H+Eb couplings and determining the experimental value of tan p. To appear in the...
